+Summary: gmcs crashes when compiling incorrect code with missing variable name for generic type
+
+Description of Problem:
+gmcs always crashes with NullReferenceException when compiling (incorrect)
+code with a generic type with object name omitted.
+
+Steps to reproduce the problem:
+Compile this code:
+
+using System.Collections;
+using System.IO;
+using System;
+ 
+public class GenericTest<T> {
+  public GenericTest(T value)
+  {
+    Console.WriteLine(value.ToString());
+  }
+ 
+}
+ 
+public class GenericTestDriver {
+ 
+  static int Main()
+  {
+    // Problem is here:
+    GenericTest<int> = new GenericTest<int>(32);
+    return 0;
+  }
+ 
+}
+ 
+
+Actual Results:
+ALPHA SOFTWARE: Mono C# Compiler 0.95.0.0 for Generics
+ 
+Unhandled Exception: System.NullReferenceException: A null value was found
+where an object instance was required.

+Expected Results:
